The CraftBlock class is setting bit 0x4 of the update flag when bit 0x2
should in fact be set here. Bit 0x2 means "do updates"; bit 0x4 means
"don't do updates if the world is static, even when bit 0x2 is set".
Currently there are several cases where a player will have their inventory
screen closed client side but we will not call an event. To correct this
we call the event when the server is the cause of the inventory closing
instead of just when the client is the cause. We also ensure the server is
closing the inventory reliably so we get the events. Additionally this
commit also calls the event when a player disconnects which will handle
kicks, quits, and server shutdown.
Two connection status checks were added to setting a scoreboard for a
player. The first checks to see if a player has logged in yet, which
implicates the ability to receive packets. The second checks to affirm
that the CraftPlayer reference is still to a logged in player; setting
it while not logged in would maintain a stale player reference in the
scoreboard manager.
The method getTeam gets the team from name of, as opposed to getting the
team a player belongs to.
This also addresses BUKKIT-4002 and partially BUKKIT-4044
When a world is created using our API, it does not use secondary world
server and will maintain a reference to its own scoreboard. In vanilla,
this is not an issue as there is only ever one world.
Similarly to maps, an overwrite to the scoreboard reference has been
added for when another world has been created.
This should also address BUKKIT-3982 and BUKKIT-3985
This implementation facilitates the correspondence of the Bukkit Scoreboard
API to the internal minecraft implementation.
When the first scoreboard is loaded, the scoreboard manager will be created.
It uses the newly added WeakCollection for handling plugin scoreboard
references to update the respective objectives. When a scoreboard contains no
more active references, it should be garbage collected.
An active reference can be held by a still registered objective, team, and
transitively a score for a still registered objective. An internal reference
will also be kept if a player's specific scoreboard has been set, and will
remain persistent until that player logs out.
A player's specific scoreboard becomes the scoreboard used when determining
team structure for the player's attacking damage and the player's vision.
This class is designed to be an invisible layer between a normal collection,
and one that silently loses entries because they are only weakly referencable.
Some operations have additional overhead to be semantically correct, but it
maintains the equals contract for all entries, as opposed to identity.
It does not support the equals or hash code method as it cannot easily have
the transitive and commutative properties.
When an array of an inventory's contents is requested, we loop through the contents of the NMS inventory's ItemStacks in order to return Bukkit ItemStacks that can be used through the API. However, the NMS ItemStack can, in some cases, be larger than the physical size of the inventory. Using the size of the NMS array as a limit on the loop that follows can result in an ArrayIndexOutOfBoundsException because the Bukkit array's length is the actual size of the inventory, and thus will be smaller.
With this commit we use the smaller of the two arrays' length as the limit in the loop, thus eliminating the possibility that the smaller array will be asked for an index higher than its length.
When a block placement happens we currently update physics on the
attempted placement and update again if the placement is cancelled.
To correct the first one we simply set the block without applying
physics. To correct the second we have to add a new method to
BlockState that lets us update without applying physics and use
this method method when putting the block back.
Without this check, any non-null reference to a plugin is considered
'valid' for registering a task in the scheduler. This is obviously
unintentional behavior and has been changed to throw an
IllegalPluginAccessException. It is now consistent with the
SimplePluginManager event registration contract.
This in affect also addresses BUKKIT-3950 for uninitialized plugin
references (ones without a description).
When cloning an item, all references are copied to the new item. For
collections, this makes internal changes become visible in both the old and
new items.
In CraftMetaItem, clone was not making copies of the appropriate collections
and has been fixed for non-null values.
In CraftMetaEnchantedBook and CraftMetaPotion, clone was using possible empty
collection references and has been changed to explicitly null-check instead.
The client resets all formatting after a color code is received, but currently the ANSI codes do not, and so the console does not accurately reflect the appearance of the formatted text. Instead, the ANSI color codes are now set to reset all text attributes.
CraftServer methods that implement the Server interface will throw an
IllegalArgumentException if a method cannot operate on a null input
and given a null pointer.
This causes methods to fail early and identify that a plugin is
responsible for passing in an invalid argument. This will only
change the exception thrown, if there originally was a thrown
exception. This helps with hunting down legitimate problems
with CraftBukkit.
